If maintenance or repair work has been carried out on 
the lift table, a function check must then be carried out.

If the lift table is used 

very frequently

 or regularly under 

"

difficult operating condition

s" (e.g. in particularly dusty 

environments, under the influence of chemicals or 
vapours, etc.), the inspection should be carried out at 
shorter intervals.

If you have any questions about the condition of the lift 
table, please contact a specialist workshop.

If the lift table does not function properly, contact a spe-
cialist dealer or our customer service. Contact details 
can be found in chapter 1.2 Customer service.

All protective and safety devices must be reinstalled im-

Step 1: Lubricate all moving parts of the lift table with 

high quality grease.

Step 2: Check the lift table for external damage before 

each use.

Step 3: Models HT 600 and HT 600 LAP: Check the hy-

draulic oil level at regular intervals.

Step 4: Make sure that all safety notices on the lift table 

are clearly legible.

pump tank filler neck. 

For oil change: Drain used oil.

Step 2: Top up oil (HLP 32) if necessary or when 

changing oil. Oil tank volume: 1 litre. 

Oil quantity in the hydraulic cylinder: 
max. 0.66 litres.

Step 3: Close the filler neck and lift and lower the lift 

table several times. Check the oil level again 
and screw in the screw plug again.

Step 4: Bleed the hydraulic system (see "Venting").

After some time, or after filling with oil, air bubbles may 
form in the hydraulic system of the lift table and affect its 
function.

Step 1: Lower the lift table to min. height

Step 2: Slowly and carefully open the oil filler plug to 

allow the trapped air to escape.

Step 3: Check the lift table for proper function, repeat if 

necessary.

Oil, grease and cleaning agents are ha-

zardous to the environment and must not
